METHOD F WEAVING'.

Specication. of Letters Patent.

Patented Feb. 25, 1919.

Application filed April 26, 1918. Serial No. 231,005.

i To all 'whom t may concern:

. ple ribbons having Be it known that I, DANIEL PATRICK, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a certain new and useful Method of Weaving, 0f which the following is a specification.

In the weaving of certain goods, for exama warp of silk and a weft or lling of cotton or other inferior material, it is a considerable element of economy to obtain whatI is termed cover, to (wit,`the hiding or covering of the lling by the warp with the use of as little as possible of the superior material which constitutes the warp, it requiring the highest skill of the designer to provide for such a disposition of the .warp threads that with the very least expenditure of warp the woven goods shall as nearly as possible have the appearance of being composed entirely of the same material as the wvarp.

The principal obj ect of this-invention is to provide a method of weaving whosel product shall present better cover and more perfect attainment of certain other desirable qualities (such as elimination of the spaces that may be detected in woven goods when held up to the light) than goods Woven according to the known methods, and in addition an edge which shall be free of loops and otherwise nicely finished.

To this end my invention contemplates laying from time to time a filling in the -warp shed before, and a separate lling in the warp shed after, a cross formed in the warp, and then beating up the fillings and intervening cross to the fell of the cloth.

The experienced weaver will see that according to this invention the reed in beating up not only advances to the fell of the cloth a greater quantity of material than heretofore-to wit, the two fillings and the .Warpcross intervening between them-but that the warp takes part in the beating up by virtue of such cross, which in effect becomes a running cross during the beating up; and because there is more material to be interposed between the fell and the reed at the limit of the beating-up movement and because the warp itself, by virtue of its cross,

Y is made directly subject to the beating-up action of the reed the weaving is very favorably modified and so caused to result in a woven product having the superior characteristics hereinbefore indicated. In view ofthe following explanation it will further be clear that a nicely finished edge may, according to this invention, be produced.

The invention is diagrammatically illustrated in the accompanying drawings, wherein,

Figures 1 to 4: show the different steps in a single cycle of mymethod of weaving; and

Fig. 5 is a longitudinal magnified section of the fabric, shed and filling substantially as these parts are related in the step illustrated by Fig. 3.

The cloth is represented by a, the shed by b, the fell of the cloth by c, the beating up medium, or reed, by d, the fillings by e e and the filling supplies, or shuttles, movable through the warp sheds, by f f. It will be understood from the drawings that the reed d is moved toward and from the fell of the cloth in any manner, as by the usual reciprocating lay or batten (not shown)l It will also be understood that means (not shown) is utilized to form a succession of sheds in the warp and in consequence a succession of crosses or decussations.

Fig. 1 shows the reed up to the fell c, that is, at its forward or beating-up limit, and the new shed being formed, that is, the parts bY of the warp shed, which before the last filling length became beaten up by the reed to form the fell of the cloth respectively occupied upper and lower positions, now respectively occupying lower and upper positions, so that the consequent cross holds said filling length in its beaten-up position.

In Fig. 2 the reed has r-eceded and the shed shown partially developed in Fig. 1 is now more or less fully developed; and in Fig. 3 the reed is shown still retracted and the shed shown is that which is formed immediately after that illustrated in Fig. 2, in consequence producing (as will appear) a cross at g.

Upon the shed illustrated by Fig. 2 being formed the filling supply f is projected through such shed and leaves a length 71, of filling therein. Then, after the shed illustrated in Fig. 3 is formed, incidentally producing the cross g, the filling supply f is projected through the latter shed as shown in Fig. 3 and leaves a length i of filling therein.

The reed now moves forward and in dopushes or beats up the filling lengths it and the warp cross g intervening ing so z and between them to the old fell c. Of course the warp cross g tends in the very act of forming more or less to advance the filling length It to the old fell c of the cloth, but not effectually, as is illustrated by Fig. 5, where it is diagrammatieally shown that at the-left of the old felle the filling length t and the warp are not so compactly related to each other as the filling lengths and warp in the finished fabrictothe right of the old fellgthe effectual advance of the filling length v/ to the old fell- 0 comes when, as aforesaid, the reedf effects thev 'beating up with respect to the filling lengths z" and h and the intervening warp Cross g. This com-l pletesA a cycle, all parts being again in the positionV shown by Fig. s 1.

My method Lof-1 weaving' has this advantage overlayingin two.v successive sheds before eachr beating up` twoy filling lengths forming parts of the same filling (from only one shuttle), as I am.. advised has heretofore been.v proposed, to wit:

The principal advantage attained-by` using separate fillings insteady of only one is this:V When only a singlev filling is used, to4 bev projected throughl the shed, followed by acrossing of the. warpthreads, andi then-.projected back through the shed, the lengthzof' filling first laidin simply reposes'bacl of the cross without being beaten comes a part of the cloth, sorthat looping;40

is not possible. and the edges. are regularly formed;

Hfzwingethusfully described my invention, what Il claimA as ne-wi and desire stoof secure, by Letters Patent is r Y The method of weavingshereinl described consisting insuccessively forming erosses in the warp and also performing the fol-l lowing stepsfromtimev to time, to Wit: passing a filling through and thereby layingla i primary lengthof.- filling` in theI warpv shed before, and passing .a separate llingfthrough and therebyr laying a secondary length of filling in the warp shed after, ai cross, ,and

beating up. the primary: andsecondary fill.-

ing lengths andiV intervening crossitoltliefell. of the cloth. v
